Hi friends.
Recently I setup a new IBM Thinkpad T61 with NetBSD 5.0 Stable (amd64
port) and xorg from -current.
I have gnome installed and working partially.
I start gnome via .xinitrc script and xinit from the command line putting
exec dbus-launch --exit-with-session gnome-session&
Gnome start ok, but the appearence don't work fine and other fine
programs, such as brasero.
The famd daemon don't run, it say: "famd[3538]: can't register with
portmapper." at the time to run "evince", per example.
is here another tip for running it via .xinitrc or may need compile
famd once more time.
I can apreciate your advices.
Regards.

Why don't you start it with gdm?
If you decide to do things manually, you are pretty much "on your own".
